The Infinity Ring was invented/developed by Dak Smyth's parents and finished by Sera Froste in A Mutiny in Time in an attempt to accomplish time travel. The Hystorians were funding the research of the ring (without the knowledge of the Smyth's) and immediately went to retrieve it after the test run by Dak, his parents and Sera. There is currently one Infinity Ring in existence and it can only be piloted by 4 people: Dak Smyth, His father, his mother and Sera. The Infinity Ring can create a wormhole that can send a limited amount of mass to any time period as long as the device is programmed to that time. Anything or anyone touching the pilot of the Ring will also be transported through the wormhole.
